The conduit cover can �� be used with ½" or ¾" diameter conduit. 2. Slide the Conduit Cover on the bottom edge of the controller. �� Conduit Cover � � � � � � � � 3. Bring the conduit and field wires to the bottom of the controller. Make sure that there is a sufficient length of conduit so it enters the Conduit Cover. There are two small notches on the left side of the cover to route the 24VAC wires from the external transformer, or wires from the sensor and P/MV (if applicable). 4. Secure the Conduit Cover to the wall with the screws and anchors provided. 5. Replace the lower access panel on the EC. MOUNTING THE OUTDOOR CONTROLLER TO WALL ....................................................... NOTE: Outdoor model is water and weather resistant. Connecting the outdoor EC to the primary power should only be done by a licensed electrician following all local codes. Improper installation could result in shock or fire hazard. A B 1. Select a location that is conveniently close to a power supply. 2. Make sure to abide by all electrical and installation codes when attaching to an external wall. 3. Place the controller at eye level and align keyhole (A) on top of the controller and mark the spot as well as the three holes (B) on the bottom of the unit. 4. Drill a 6 mm hole at each mark. 5. Install screw anchors (C) into holes if attaching controller to drywall, masonry, or plaster walls. 6. Holding the controller cabinet, line up the holes in the cabinet with the wall anchors or pilot holes. 7. Drive a screw through each hole and secure snugly but do not over tighten. C 7 CONNECTING VALVES AND TRANSFORMER .................................................................... 1. Route control wires between valve location and controller. Typically it is recommended that at least 1 mm diameter conductor cable be used. This type of cable is insulated for burial and is color-coded to help keep track of your connections. 9. For the outdoor model, transformer wires are already connected to the AC slots so all that is required is to connect primary power to the junction box from a power source. 10. Remove junction box cover and attach power wires to either screw slot. Be sure to use a code approved conduit and adapter for the primary wires. 2. At the valves, attach the common wire to either solenoid wire of the valve. This is most commonly a white colored wire. Attach a separate control wire to the remaining solenoid wire and make a note of the color corresponding to each valve and the watering station it controls. Do not plug transformer into power source until the controller is mounted and all valves have been connected. 3. Secure the wires with a waterproof wire connector to protect the connection. 4. Slide down wiring compartment door to access the terminal strip area shown in the diagram. Valve 4 5. Route the valve wires into the cabinet. Strip 5 mm of insulation from ends of all wires. 6. Secure the white valve common wire to the screw on the terminal marked C. Connect the color-coded wires from the valves to their appropriate station numbers and tighten the screws. 7. For the indoor model, route transformer cable through the left side of the controller and connect the wires to the two screws marked AC. 8. Before closing the compartment door make sure wires hang in the slotted areas so that the door can snap shut without damaging wires.

Wire Clip Battery Compartment Connect a 9-volt alkaline battery (not included) to the battery wire clip located in the lower left-hand side of the controller. The battery will allow you to program the controller without AC power. However, the battery will not be able to activate any of the station valves. AC power must resume before watering will continue. SEASONAL ADJUSTMENT WATER DAYS SEN AC C P 1 2 3 4 5 6 RST 9 V Battery CONNECTING A MASTER VALVE .......................................................................................... NOTE: Complete this section only if you have a master valve installed. A master valve is a “normally closed” valve installed at the supply point of the main line that opens only when the controller initiates a watering program. 1. At the Master Valve, attach the common wire to either solenoid wire of the valve. Attach a separate control wire to the remaining solenoid wire and make a note of the color corresponding to the master valve. Valve 4 SEASONAL ADJUSTMENT WATER DAYS SEN AC 9 V Battery C P 1 2 3 4 5 6 Valve 3 RST Master Valve Wire Valve 2 2. Route these wires to the controller the same way as the station valves. The white common wire will still go to the screw slot marked C. The additional wire coming from the master valve will go in the screw slot marked P. Valve Wires Valve 1 Master Valve Valve Common Wire 9 CONNECTING A PUMP START RELAY ................................................................................. NOTE: Complete this section only if you have a pump start relay installed. A pump start relay is a device that uses a signal from the controller to actuate a separate electrical circuit to energize a pump to provide water to your system. 1. Route a wire pair from the pump relay into the controller housing. 2. Connect common wire to the screw slot C (Common) and the remaining wire from the pump relay to the P screw slot. Relay holding current draw must not exceed .28 Amps. Do not connect controller directly to pump—damage to controller can result. The controller should be mounted at least 4.5 m away from both the pump start relay and the pump. When a pump start relay comes on it sends out surges that may potentially cause damage to a controller that is mounted too close. When a pump is to be operated by the controller, a pump start relay must be used. Hunter offers a full range of pump start relays for most applications.

A Hunter Mini-Clik ® rain sensor or other type of micro-switch weather sensor can be connected to the EC. The purpose of this sensor is to stop watering when weather conditions dictate. 1. Remove the jumper that is attached across the SEN terminals of the controller. Weather Sensor SEASONAL ADJUSTMENT WATER DAYS SEN AC 9V Battery C P 1 2 3 4 5 6 RST 2. Route the two wires from the rain sensor up through the same opening used for valve wiring. 3. Connect one wire to the SEN terminal and one to the other SEN terminal. NOTE: If the rain sensor is interrupting irrigation you can bypass it by using any of the following: MANUAL-ONE STATION, MANUAL-ALL STATIONS, or ONE TOUCH START AND ADVANCE. See section “Rain Sensor Bypass” for more information. POWER FAILURES ................................................................................................................... Due to the possibility of power failures, the controller has non-volatile memory. Programmed information will never be lost. The controller will keep the correct time for up to 1 month without power. Normal watering will resume when AC power is restored. 11 SPRINKLER SYSTEM FUNDAMENTALS ............................................................................. There are three main components that are involved with all automatic sprinkler systems that are made today. They are the controller, control valves, and the sprinklers. amount of water that can be pumped to the location. Each valve is connected via wire to the terminal strip area inside of the controller. Here the wire is connected to a number that corresponds to the valve’s station number. The controller is what makes the whole system operate efficiently. It is technically the brain of the entire system, instructing the valves when to supply water to the sprinklers and for how long to do so. The sprinklers, in turn, will direct the water towards the surrounding plants and lawn. The controller will operate the valves in order, only one at a time. When a valve has completed its watering; it will switch to the next station that has been programmed. This process is called the watering cycle. The information pertaining to the watering times of the individual stations and how often watering occurs is called a program. The valve controls a group of sprinklers called a watering station. These stations are laid out in a fashion according to the type of plant life that exists there, the locations of the plants, and the maximum EC Controller Valve 1 Valve 2 AUTOMATIC Station 2 ® SYSTEM OFF MANUAL-ALL STATIONS MANUAL-ONE STATION ALL 1 SEASONAL ADJUSTMENT Valve 3 EC CURRENT TIME/DAY START TIMES ® RUN TIMES WATER DAYS Station 1 ® Valve 1 – Activates Station 1 – Rotors water front yard lawn Station 3 Valve 2 – Activates Station 2 – Sprays water side lawn and bubblers water flowers Valve 3 – Activates Station 3 – Rotors water back yard lawn Valve 4 – Activates Station 4 – Bubblers water garden ® ® Valve 5 – Activates Station 5 – Sprays water side lawn and bubblers water flowers Valve 6 – Activates Station 6 – Sprays water front corner lawn 12 Station 6 Valve 6 Station 4 Station 5 Valve 5 Valve 4 ® PROGRAMMING FUNDAMENTALS ..................................................................................... 6 Sprinklers at Station 1 begin to water at 6:00 AM Sprinklers at Station 1 turn off at 6:15 AM Station 2 12 9 3 6 Sprinklers at Station 2 begin to water at 6:15 AM Sprinklers at Station 2 turn off at 6:30 AM Station 3 12 ® For example, using more than one program would enable you to water on odd days for lawn stations 1, 2, and 3 on program A, station 4 to soak the flowers every day on program B, and station 5 and station 6 to water on even days on program C. However, it is not absolutely 3 ® We realize that many consumers will have variations in their plant watering needs, so at Hunter we equipped the EC with three different programs A, B, and C. These programs are completely independent of each other and give you the ability to have three coexisting timers in one controller. 9 ® As shown in the above example, only one program start time was required to run the three different stations. The controller automatically moves to the next station without the need for additional start times. 12 Program Begins at 6:00 AM ® Going back to our previous example, at 6:00 am the controller will activate the watering cycle. The sprinklers on station 1 will run for 15 minutes and then automatically shut off. The controller will automatically activate station 2 sprinklers. These sprinklers will also run for 15 minutes and then shut off. Then, watering on station 3 will begin automatically. The sprinklers will turn on for 20 minutes and shut off automatically. Since no times were programmed for stations 4 and 5, the controller skips them. This will conclude the program and end the water cycle at 6:50 am. Station 1 ® We have included an example that will better illustrate the operation of a program. Let’s say you have a program start time set for 6:00 am. Stations 1 and 2 are going to have a run time of 15 minutes and station 3 is set for 20 minutes. Please note that stations 4 and 5 have not been included in this program, we will water them on separate programs. necessary to use this feature. Many homes and businesses can have all zones adequately watered on one program with the other programs turned off for future use. ® For the controller and it’s selected program to operate automatically, there are three components that must exist: 1. When to water—or Watering Start Times. 2. How long to water—or Station Run Times. 3. What day of the week to water—or Days to Water. 9 3 Program Ends at 6:50 AM 6 Sprinklers at Station 3 begin to water at 6:30 AM Sprinklers at Station 3 turn off at 6:50 AM 13 CREATING A WATERING SCHEDULE ................................................................................... For most consumers, it is much easier to plan your specific watering schedule onto paper before actually programming the information into the controller. It’s also handy to have a written record of your programming information for easy reference. There are some guidelines that should be followed when determining when and how long to water. These factors are the soil type, the part of the landscape being watered, weather conditions, and the types of sprinklers being used. Since there are so many different variables that can determine your individual watering schedule, it is impossible to give an exact schedule to follow. However, we have included some guidelines to help you get started. It is usually good to water one or two hours before sunrise. Water pressure will be at optimum levels during the early morning and the water can soak into the roots of the plants while evaporation is minimal. For most plants, watering during midday or in the evening may cause plant damage or possibly mildew. Keep an eye out for evidence of under- or over-watering. Over-watering is most commonly indicated by pools of water that take a long time to soak in or evaporate, while under-watered landscapes will show signs of discoloring and dryness. Make programming changes immediately when evidence is present. HOW TO FILL OUT THE WATERING SCHEDULE FORM Be sure to use a pencil when filling out this form. By using the included example and the information below, you should have all the information you need to construct your personal water schedule. Program Start Times – Indicate the time of day that the program will begin. Each program can have 1 to 4 start times. However, one start time can run an entire program. Station Number and Location – Identify the station number, location and the type of plant that is being watered. Station Run Time – Indicate the run time (1 minute to 4 hours) for each station. Write “OFF” for any station that you do not want to operate in the program. Watering Day – Identify whether you want to use a calendar day or an interval day schedule. For a calendar day schedule circle the day of the week in which watering is desired. For an interval day schedule, simply set the corresponding number of days. 14 Keep this schedule in a safe place for quick reference later, rather than scrolling through program information on the controller.

The EC Controller is easy to program. The easy to understand dial design allows you to step through the process of programming and activate manual watering with a twist of the wrist. Setting the Date and Time The EC display shows time and day when the controller is idle. The display changes when the dial is rotated to indicate the specific programming information to enter. When programming, the flashing portion of the display can be changed by pressing the or buttons. To change something that is not flashing, press the button until the desired field is flashing. 2. Hours will be flashing. Press the or button to change the hour shown on the display. Press the to proceed to setting the minutes. Three programs A, B and C each with the ability to have four daily start times, permit plants with different watering requirements to be separated on different day schedules. Multiple start times permit morning, afternoon, and evening watering, perfect for the establishment of new lawns and thirsty annual flowers. Simply designate the days of the week you want to water. The EC makes it easy. NOTE: A basic programming rule is that whatever symbol or character is flashing will be the item programmed. For instance, if the hour is flashing when setting the time, the hour can be changed or programmed. For illustration purposes, flashing characters are in GRAY type. CURRENT TIME/DAY 1. Turn the dial to the CURRENT TIME/DAY position. 3. Minutes will be flashing. Use the or button to change the minutes shown on the display. Press the to proceed to select AM, PM, or 24 hour time. 4. The time will be displayed, and an arrow will be flashing on and butAM. Press the tons to select AM, PM, or 24 hour. Press the to proceed to setting the day of the week. 5. The MO (for Monday) will be flashing. Press the and to select the day of the week corresponding to the day. The time and day have now been set. You can turn the dial to AUTOMATIC to display the current time. MO TU WE TH FR SA SU * Note: For -E models of EC controllers, days of the week are indicated by numbers 1 through 7. 17 PROGRAMMING THE CONTROLLER (continued) .............................................................. Setting Watering Start Times 1. Turn the dial to the START TIMES position. Eliminating a Program Start Time START TIMES 2. The factory preset is set on program A. If necessary, you can select program B or C by pressing the button. 3. Use the or button to change the start time. (The start times advance in 15 minute increments). Hold either button down for 1 second to change times rapidly. button to select 4. Press the the next start time, or press for the next program. NOTE: One start time will activate all stations sequentially in that program. This eliminates the need to enter each station’s start time. Multiple start times in a program can be used for separate morning, afternoon, or evening watering cycles. 18 With the dial set to the SET WATERING START TIMES position, push the or button until you reach 12:00 am (Midnight). From here push the button once to reach the OFF position. START TIMES NOTE: If a program has all four-start times turned off, then that program is off. (All other program details are retained.) Because there are no start times, there will be no watering with that program. This is a convenient way to stop watering on one program only without turning the dial to the OFF position. Setting Station Run Times (Length of Watering for Each Area) Setting Days To Water 1. Turn the dial to the RUN TIMES position. 1. Turn the dial to the WATER DAYS position. 2. The display will show the last program selected (A, B or C) the station number selected, run time icon, and the run time for that station will be flashing. You can switch to another program by pressing the button. RUN TIMES 3. Use the or button to change the station run time on the display. 4. Press the button to advance to the next station. 5. Repeat steps 3 and 4 for each station. 6. You can set station run times anywhere from 0 to 4 hours. 7. You can move between programs while staying on the same station. However, it is recommended that one program is completed before going on to the next program. NOTE: Jumping between programs can be confusing and may result in program entry errors. 2. The display will show the last program selected (A, B or C). You can switch to another program by pressing the button. WATER DAYS 3. The controller will display the seven days of the week with a icon or a icon above the numbered day. The icon would represent an “On” water day, while a icon would represent an “Off” watering day. Selecting Speciﬁc Days of the Week to Water 1. With the cursor on a specific day (the cursor always starts with MO), press the button to activate a particular day of the week to water. Press the button to cancel watering for that day. After pressing a button the cursor automatically advances to the next day. MO TU WE TH FR SA SU 2. Repeat step 1 until all desired days have been selected. The selected days will show with a to indicate their status as ON. The last is the last day of watering for that program. 19 PROGRAMMING THE CONTROLLER (continued) .............................................................. Selecting Interval Watering System Off With this option you can select interval watering from 1 to 31 days. Valves currently watering will be shut off after the dial is turned to the SYSTEM OFF position for two seconds. All active programs are discontinued and watering is stopped. To return controller to normal automatic operation, simply return dial to AUTOMATIC position. 1. With the cursor on day 7, press the button until the two calendars and a flashing 1 appear in the display. Interval watering schedule appears on the display. Programmable Rain Off 2. Press the or button to select the number of days between watering days (1 to 31). This is called the interval. The controller will water the selected program at the next Start Time and will then water at the interval programmed. Example: You program the controller at 8:00 am for the following: Program A SYSTEM OFF This feature permits the user to stop all programmed waterings for a designated period from 1 to 7 days. At the end of the programmable rain off period, the controller will resume normal automatic operation. 1. Turn the dial to the SYSTEM OFF position. Wait for OFF to be displayed. button and a 1 will be 2. Press the displayed. The 1 will be blinking at this point. Start Time 10:00 am Interval = 5 days The controller will run on today at 10:00 am and water program A. Then, the controller will wait 5 days and water again at 10:00 am and so on. 3. Press as many times as needed to set the number of days off desired (up to 7). Had you programmed the controller at 11:00 am rather than at 8:00 am, the controller would have watered tomorrow at 10:00 am and then watered every 5 days after that at 10:00 am. 4. To validate this setting (and to make sure the controller comes back on after the period is over), turn the dial back to the AUTOMATIC position at which time, OFF, a number and the DAYS icon all remain on. Automatic After programming is complete, turn the dial to AUTOMATIC to enable automatic execution of all selected programs and start times. Watering will not occur unless dial is in the AUTOMATIC position. 20 SYSTEM OFF AUTOMATIC 5. Leave the dial in the AUTOMATIC position. The days off remaining will decrease at midnight of each day. When it goes to zero, the display will show the normal time of day and normal irrigation will resume at the next scheduled start time. AUTOMATIC NOTE: Due to variances in pressure and flow, valve may take up to one minute to fully close. Bypass Weather Sensor If there is a weather sensor installed that is interrupting irrigation, you can bypass it by using the manual watering options described below. The dial positions MANUAL-ONE STATION and position MANUAL-ALL STATIONS as well as the One Touch Start and Advance process will successfully bypass the rain sensor. Seasonal Adjustment Seasonal Adjust is used to make global run time changes without re-programming the entire controller. SEASONAL ADJUSTMENT This feature is perfect for making small changes that are necessary as the weather changes without reprogramming the entire controller. For instance, hotter times of the year may require a bit more water. Seasonal adjust can be increased so that the stations will run longer than the programmed time. Conversely, as Fall approaches, the seasonal adjust can be reduced to allow for short watering durations. To use the seasonal adjustment feature: 1. Turn the dial to the SEASONAL ADJUSTMENT position. 2. The display will now show a flashing number followed by a %, as well as the bar graph which always remains on the display. Press the or buttons to adjust the percentage of the seasonal adjustment. Each bar on the graph represents 10%. This feature can adjust the controller from 10% to 150% of the original program. To view the new adjusted run times, simply turn the rotary dial to the SET STATION RUN TIMES position, the displayed run time will be updated accordingly as the seasonal adjustment is made. NOTE: The controller should always be initially programmed in the 100% position. Manually Run a Single Station 1. Turn dial to the MANUAL-ONE STATION position. MANUAL-ONE STATION 1 2. Station run time will flash in the display. Use the button to move to the desired station. You may use the or select the amount of time for a station to water. button to 3. Turn the dial clockwise to the AUTOMATIC position to run the station (only the designated station will water, then the controller will return to automatic mode with no change in the previously set program). Also see One Touch Manual Start and Advance on page 22. Manually Run All Stations 1. Turn dial to MANUAL-ALL STATIONS. MANUAL-ALL STATIONS ALL 2. Select program A, B, or C by pressing the button. 3. Press the button until desired starting station is displayed. 4. Station run time will flash in the display. Use the or button to select the amount of run time for the station to water if different from the run time displayed. 5. Use the button to move to the next station. 6. Repeat steps 3 and 4 to customize each station if desired. 21 PROGRAMMING THE CONTROLLER (continued) .............................................................. 7. Press the button until you reach the station that you would like watering to begin. One Touch Manual Start and Advance 8. Return dial to AUTOMATIC (program will water the entire program beginning with the station number last left in the display, then controller will return to automatic mode with no change in the previously set program). 1. Hold down the NOTE: The station that is on the display when you turn the dial to AUTOMATIC will be the first station to run. The controller will then proceed to water in sequential order only. It will not water previous stations. Example: If you turn the dial to AUTOMATIC with the display reading station 3, the controller will water stations 3 through 6 in the program, but not return to stations 1 and 2. You can also activate all stations to water without using the dial. button for 2 seconds. 2. This feature automatically defaults to program A. You can select program B or C by pressing the program. button to scroll 3. The station number will be flashing. Press the through the stations and use the or button to adjust the station run times. (If no buttons are pressed for a few seconds during step 2 or 3, the controller will automatically begin watering.) 4. Press the button to scroll to the station you wish to begin with. After a 2 second pause, the program will begin. This feature is great for a quick cycle when extra watering is needed or if you would like to scroll through the stations to inspect your system. HIDDEN FEATURES ................................................................................................................. Programmable Delay Between Stations This feature allows the user to insert a delay between when one station turns off and the next station turns on. This is very helpful on systems with slow closing valves or on pump systems that are operating near maximum flow or have slow well recovery. AUTOMATIC 5. Return the dial to the AUTOMATIC position. 1. Start with the dial in the AUTOMATIC position. Clearing the Controller's Memory/ Resetting the Controller 2. Press and hold the button down while turning the dial to the SET STATION RUN TIMES position. If you feel you have misprogrammed the controller, there is a process that will reset the memory to factory defaults and erase all programs and data that has been entered into the controller. 3. Release the button. At this point the display will show a delay time for all stations in seconds, which will be blinking. The DELAY icon shall also be lit at this time. 22 AUTOMATIC 4.

See "Setting Watering Start Times" (p. 18) Controller waters the same area more than one time/Controller cycles continuously. 24 FREQUENTLY ASKED QUESTIONS ....................................................................................... 1. WHY DOES MY SYSTEM CONTINUE TO CYCLE THROUGH OVER AND OVER? You may have too many start times entered. Only one start time is needed to run a program. See section titled “Start Times.” 2. DO I NEED A START TIME FOR EVERY STATION? No! You only need one start time per program. The program runs sequentially, so the proceeding station will automatically start when the previous station is finished, no need for additional start times. Multiple start times are utilized when you desire to water an entire program more that once in a 24-hour period. 3. WHY ARE THERE THREE DIFFERENT PROGRAMS (A, B, AND C)? These three programs exist for a variety of reasons. Since customers needs vary from each location, it is important to make sure that even the largest landscapes can be properly irrigated. Most consumers can fulfill their needs with a single program and a single start time, but others who have a variety of different plant life may need more than one program and several start times. See the section “Programming Fundamentals” for more information. 5. WHY IS THE ON “MO” EVERY TIME I TURN THE DIAL TO “WATER DAYS”? The always flashes on MO when you turn the dial to this position. When finished setting the days you want, turn the dial to any position. When you go back to WATER DAYS you will see the lit over the days you have chosen. 6. AN INDIVIDUAL STATION WON’T SHUT OFF. WHAT DO I DO? When one particular station is stuck on, you want to shut off the controller by turning the dial to the off position. If the station is still running, you will need to shut off the main water supply to the sprinkler system. Most likely there is a valve stuck open, caused by debris in the valve. A loose solenoid or loose valve cap may also be the problem. Check these connections or call your contractor for assistance. 4. WHAT ARE THE DIFFERENCES BETWEEN PROGRAMS A, B AND C? They all have the same features and functions. Three programs give you the option to have several different types of plants watered at different days and times. See “Programming Fundamentals” for more information. 25 SPECIFICATIONS .....................................................................................................................
